Insulating materials can acquire a static electric charge. Rubber balloons, when rubbed on woolen cloth, are a perfect example.
The electric field inside a charged insulator is zero, while the electric field outside a charged insulator is non-zero.
Inside a charged insulator, the electric field is 0, as charges cannot move freely in insulators. Outside the insulator, the electric field behaves as if all the charge is concentrated at the center of the insulator.
When a charged insulator is placed near an uncharged metallic object, the charges in the insulator induce opposite charges in the metallic object through electrostatic induction. This causes the metallic object to become polarized, with one side becoming positively charged and the other side becoming negatively charged. The presence of the insulator affects the behavior of the metallic object by creating an attractive force between the opposite charges, causing the metallic object to be attracted towards the charged insulator.
Insulators can be charged by coming into contact with a charged object, inducing a separation of charge within the insulator. This can happen through processes such as friction, conduction, or induction, leading to the insulator having a net positive or negative charge.
When an electric insulator becomes charged, it is typically due to the transfer of electrons from one object to another. This can occur through processes such as friction, induction, or contact. Once charged, the insulator can hold on to these excess electrons, leading to a build-up of static electricity.

I believe they'd are positively charged.
A charged insulator can be neutralized by grounding it, which involves connecting it to the Earth's surface with a conductor. This allows the excess charges to flow away, leaving the insulator with zero net charge. Alternatively, you can also neutralize a charged insulator by introducing an opposite charge to cancel out the excess charges.

Passing a charged insulator above a flame can create ions in the air near the insulator due to the high temperature of the flame. These ions can neutralize the charged insulator, allowing it to discharge. The process relies on the ions transferring their charge to the insulator, thereby removing its excess charge.

An insulator Becomes statically charged when rubbed against another insulator
Because there is no insulator attached to it to prevent escape of charge.
The material between two charged bodies that prevents the discharge of electricity is an insulator. Insulators have high resistivity, which inhibits the flow of electric current between the charged bodies. Examples of insulating materials include rubber, glass, and plastic.
A charged insulator can be discharged by passing it just above a flame because a flame has a cloud of ions above it. Even though the overall charge above the flame is neutral, a charged insulator will use up the ions that it needs and neutralize.
